Open Source Document Management System | OpenKM

* I suggest delete the tomcat folder and start the installation process again
* You should use MySQL, MariaDB, SQL Server, PostgreSQL or Oracle database for production environments. Our suggestion in ubuntu 20.04 is Mariadb

Hi,
I have same problem. Installing on Ubuntu 20.04 and MySQL 8.0, installed from Ubuntu repositories, server working well with other applications.
OpenKM does not connect to MySQL, and so tables are not created. In my several attempts I got database populated and access once, but as soon as the machine is restarted OpenKM never again gains dbase connection.
Tried installing in Windows 10, also with MySQL, but there the service OpenKM does not even start, giving an error 'Incorrect function'.
Installing with H2 works without problem, and survives restarting.
Replacing .war file in Tomcat with last version (6.3.9) result in same problems.
I would appreciate some help, thanks.

* stop openkm
* delete al file in the logs folder
* start openkm
* take a look at the full stack error in the openkm.log file ( share here )

Usually issue happens because by choosen enable SSL connection to mysql connection -> take a look here https://docs.openkm.com/kcenter/view/ok ... oting.html ( but may be it is another reason )
